Frequency compensation method and apparatus

An apparatus, comprising:

• at least one processor and at least one non-transitory memory, wherein
• the at least one non-transitory memory is configured to store program instructions;
• and
• when executing the program instructions, the at least one process is caused to:
• determine a Doppler frequency shift value Fa based on a weighted change rate of a change rate of a timing advance (TA) of a terminal;
• and
• perform frequency compensation for wireless communications based on the Doppler frequency shift value Fd;
• and
• wherein the Doppler frequency shift value Fa is determined using a formula:
• Fd=Kd*Δt, wherein Kd represents a change rate of the Doppler frequency shift value Fd;
• and
• the change rate Kd of the Doppler frequency shift value Fd and the TA meet:
• Kd=α*(TA(t+2Δt)−TA(t+Δt))—β(TA(t+Δt)—TA(t)), wherein t represents a time, Δt represents a unit time, and α and β represent weighting coefficients.

A non-transitory computer-readable storage medium storing computer-readable instructions, wherein when the computer-readable instructions are run on a communications apparatus, the communications apparatus is caused to:

• determine a Doppler frequency shift value Fa based on a weighted change rate of a change rate of a timing advance (TA) of communications apparatus;
• and
• perform frequency compensation for wireless communications of the communications apparatus based on the Doppler frequency shift value Fd;
• and
• wherein the Doppler frequency shift value Fa is determined using a formula:
• Fd=Kd*Δt, wherein Kd represents a change rate of the Doppler frequency shift value Fd;
• and
• the change rate Kd of the Doppler frequency shift value Fa and the TA meet:
• Kd=α*(TA(t+2Δt)−TA(t+Δt))−β(TA(t+Δt)−TA(t)), wherein t represents a time, Δt represents a unit time, and α and β represent weighting coefficient.
